Web app tracks pupil size in people, mice
The app relies on artificial intelligence and could help researchers standardize studies of pupil differences in autistic people and in mouse models of autism.
New library catalogs the human gut microbiome
Researchers put hundreds of gut bacteria strains through their paces to chart the compounds each creates — and to help others explore the flora's potential contribution to autism.
New unified toolbox traces, analyzes neurons
‘SNT’ helps researchers sift through microscope images to reconstruct and analyze neurons and their connections.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.

Molecular changes after MECP2 loss may drive Rett syndrome traits
Knocking out the gene in adult mice triggered up- and down-regulated expression of myriad genes weeks before there were changes in neuronal function.
